This unfortunate Therid spider Platnickina tincta has an unwelcome guest! A parasitoid wasp larva sits on its back & is sucking its insides out. Once the wasp larva is full grown it will suck out all of the spiders inners then pupate on its body. Dartmoor, Devon 5 May 2026 @gavinbroad.bsky.social

The battle of narratives is going strong. Our countries are a recurring target.   It is time to act to tell the stories that make us strong. Let’s live our own story! Protect what matters - our democracy.

Who describes the spiders? In this episode, I talk to Katherine Montana and Cláudia Xavier @claudiaxavier.bsky.social about their paper examining authorship in taxonomy. They analyzed thousands of species to identify patterns of underrepresentation, and shared hopes about the future of taxonomy.

Wayne Maddison (waynemaddison.bsky.social), professor emeritus at UBC, captured this video of a nearly transparent jumping spider (tribe Amycini) from Canandé Reserve, Ecuador. Look closely & you'll see the principal eyes moving as it scans the area visually. Let's talk about spider-vision! 🕷️🧪

Species descriptions should not be confined to "summary" PDFs only providing access to a fraction of the data underlying the conclusions. We here argue for "digitally native species" built around structured, specimen-linked, machine-actionable evidence from day one. rdcu.be/fcbwh

Cost-effectiveness is often determined by upfront costs. But getting to the right results faster could eliminate downstream interventions — saving time & money while improving outcomes. Mike shares how Oxford Nanopore has the potential to do this. https://bit.ly/47nLgDy

Would you like to learn about how genetic differentiation and phenotypic plasticity shape a species' range expansion? Here is a new, comprehensive paper led by Monica Sheffer from my group - supported by wonderful colleagues.

Myriapod Meet Up 2026 will be on 1 April, 8AM - 5PM (EDT). This online event will include short talks, and a chance to share and discuss research about myriapods (and other multipedes, e.g. Onychophora). Anyone may participate in this free event (no need to give a talk).

BGE is done sampling! 🥳 All over Europe scientists and citizen scientists took samples for BGE. Those samples needed to be transported to a lab for research, travelling thousands of kilometers. And that's not easy! More info on our website! 👉 biodiversitygenomics.eu/2026/01/21/b...

🦋🧬 A milestone for biodiversity genomics. Project Psyche is building chromosome-level genomes for ~11,000 European butterflies & moths — 1,000 sequenced, 3,000+ collected, across 34 countries. 🔗 Read the publication: bit.ly/ProjectPsyche @projectpsyche.bsky.social #BiodiversityGenomics 🧬🌍

Pleasure to share our discovery! 🕷️🥰 The specimens for this article were collected in Thailand in 2020 😷 Interestingly, this species was already well documented on iNaturalist, yet remained unnamed until now! @arachnology.bsky.social @arachnologynews.bsky.social @jumpingspiders.bsky.social

🧬 What are the best sampling practices to generate high-quality #genomic data? Well, it depends on the taxonomic group, of course!That’s why the #ERGAcommunity is working on taxon-specific sampling procedures. And you can join us! ➡️ www.erga-biodiversity.eu/post/samplin...

In a new ZooKeys paper, authors named a new spider genus after our subject editor and prolific author Shuqiang Li! We congratulate Shuqiang on this distinction. blog.pensoft.net/2025/12/08/a...

Real conservation action, guided by genomes! @ergabiodiv.bsky.social @biogeneurope.bsky.social Why go beyond the reference genome? Because population genomics reveals hidden risks — low diversity, genetic drift, and declining gene flow. 🌍 Wetlands are disappearing… and so is genetic diversity.

I’ve released a tool to sketch and edit phylogenetic trees! yawak.jp/PhyloWeaver/ Load a Newick file and intuitively add/remove/resize branches. Useful for quick conceptual trees, extracting subtrees, or turning ideas into Newick.

Pleased to see @markavery.bsky.social's endorsement of @ecology-digest.bsky.social's atlas of Yorkshire's spiders and harvestmen, which we funded with the Yorkshire Naturalists' Union. 'If spiders are your thing, then this is a book for you, particularly, but not only, if you live in Yorkshire'

🎉 BROKEN RECORD! 🕸️ The recent discovery of a 100,000- #spider “megacity” on the border between Greece and Albania, published in our #openaccess, peer-reviewed journal @subtbiol.pensoft.net, became the most popular article across our entire #scientific portfolio, outperforming ~27,000 articles! 👏

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.
